Now is the time of LibreOffice.

On 28 September 2010, several members of the OpenOffice.org project formed a new group called "The Document Foundation". The Document Foundation created LibreOffice from their former project in response to Oracle Corporation's purchasing of Sun Microsystems over concerns that Oracle would either discontinue OpenOffice.org, or place restrictions on it as an open source project, as it had on Sun's OpenSolaris.
It was originally hoped that the LibreOffice name would be provisional, as Oracle was invited to become a member of The Document Foundation. Oracle rejected requests to donate the OpenOffice.org brand to the project and demanded that all members of the OpenOffice.org Community Council involved with The Document Foundation step down from the OOo Community Council, citing a conflict of interest.
The Go-oo project was discontinued in favour of LibreOffice. Improvements made by the project were merged into LibreOffice. Enhancements made in other forks are also expected to be incorporated into LibreOffice. Also underway is the reduction of Java dependency, with the goal of minimizing security issues and improving application stability.
As a result of the fork of OpenOffice.org into LibreOffice, and the resulting loss of developers, Oracle announced in April 2011 that it was terminating the commercial development of OpenOffice.org. In June 2011, Oracle announced that it would contribute the OpenOffice.org code and trademark to the Apache Software Foundation, which decided to accept the offer and start an incubation process within the foundation.
Google and Red Hat began to contribute programmers to LibreOffice in June 2011.
